Crystal structure and multicomponent effects in Li1+xMn2−x−yAlyO4 cathode materials for Li-ion batteries

247The strong spinel-framework contributes to a better structure-stabilization, resulting in a superior capacity retention ratio of 90% after 200 cycles at 0.5 C at 55 °C for the optimized composition (Li1.06Mn1.86Al0.08O4), which possesses an initial value of 102 mAh g−1.
